Description

command
ERROR<Error code>
Failure
3.2.14 Re-join
Description
The module tries to re-join to a network if it loses connection to the network it
was associated with. If the re-join is successful, then the link is re-established.
The module aborts the re-join after a fixed number of re-tries. If this happens,
an asynchronous response “ERROR-22\r\n” is sent from the module to the Host.
This is not a response to a command, but an asynchronous message sent to the
Host if re-tries fail.
Message
ERROR-22\r\n

3.2.15 Disassociate
1
Description
This command is issued to request the module to disassociate (disconnect) from
an Access Point. The Host can then issue a fresh set of Scan, Join commands to
connect to a different Access Point or the same Access Point with a different set
of connection parameters. The Power Mode (0, 1 or 2) is retained from before
the Disassociate command to the next association, i.e. if the Power Mode is 1
before the Disassociate command is issued, then, after the next Join command is
successful, the module is in Power Mode 1 automatically.
Command
at+rsi_disassoc
Usage
at+rsi_disassoc\r\n
Parameters
1
This command is not supported in ad-hoc mode. For disconnecting in IBSS mode,
the module can be soft-reseted by at+rsi_reset, and then the command sequence
from at+rsi_band should be given.
